【Painting Lecture Hall】 The difference between water-based paint and wood paint

Paint is a home improvement material we often use, but many people know a lot about paint, paint is a huge system, including wood paint and water-based paint. When we use it, we often confuse it. In fact, they are different. The following editor will introduce the difference between wood paint and water-based paint.

What kind of water-based paints are there?

1. Water-based paint with acrylic acid as the main component

The main feature is good adhesion, which will not deepen the color of wood, but the wear resistance and chemical resistance are poor, the hardness of the paint film is soft, the pencil rule is HB, the fullness is poor, the comprehensive performance is general, and the construction is prone to defects. Because of its low cost and low technical content, it is the main product that most water-based paint companies put on the market. This is the reason why most people think that water-based paint is not good. The advantage is that the price is cheap.

2. Water-based paint based on the composition of propylene native and polyurethane

In addition to adhering to the characteristics of acrylic paint, it also has the characteristics of abrasion resistance and strong chemical resistance. Some enterprises mark it as water-based polyester paint. The hardness of the paint film is better, the pencil rule test is 1H, the fullness is better, and the comprehensive performance is close to the oil paint. At present, only a few domestic enterprises can produce.

3. Waterborne polyurethane paint

Its comprehensive performance is superior, the fullness is high, the hardness of the paint film can reach 1.5-2H, the wear resistance even exceeds the oil paint, and it has obvious advantages in service life and color mixing. It is an advanced product in water-based paint. Only a few professional companies have control. The German Bayer water-based paint used in Provo Castle is one of them.

4. Pseudo-water paint

When using it, it is necessary to add curing agents or chemicals, such as "hardener", "paint enhancer", "special dilution water", etc. Some can also be diluted with water, but the solvent content is very high, which is more harmful to the human body Some even exceed the toxicity of oil paints, and some companies label them as water-based polyester paints. Consumers are easy to tell.

The difference between water-based paint and wood paint

1. Purpose

Wood paint refers to paint coating applied on wood, including polyester wood paint, PE wood paint, nitro paint, UV paint, water-based wood paint, etc., is a paint that can form a film on the wood surface using wood as the construction medium The collective term for paint. Water-based paint refers to the general name for paints that use water as a solvent, such as latex paint for painting walls, water-based wood paint that can be applied by adding water to wood, and so on. These are water-based paints. To put it plainly, paints that can add water to form a uniformly compatible liquid are water-based paints.

2. Environmental protection

Ordinary wood paint uses a special thinner to adjust the viscosity of the paint. Generally, the thinner will contain a certain amount of harmful substances such as formaldehyde and benzene; while water-based paint uses water as a diluent, of course, no harmful substances such as formaldehyde and benzene, so More environmentally friendly.

3 smell

Traditional oil-based paints are diluted with thinner water or the like as a thinner, which will emit more irritating gases and are strong carcinogens; water-based paints are diluted with water, which is ordinary drinking water as a thinner, generally there is no Irritation scent disperses.

4. Price

At present, the cost of water-based paint is relatively high, and the cost of ordinary oil-based wood paint is lower than that of water-based wood paint, and the price is relatively lower.

Summary: The above is the difference between water-based paint and wood paint introduced by Xiaobian. I hope it can help you effectively. For more information, please pay attention to this website.
